You should be able to work with the DLL that is "only for C/C++", if you create
the correct set of declarations in your VB program. The declarations look like
this, which is a Windows API call example:

Declare Function SetCurrentDirectory Lib "kernel32" Alias "SetCurrentDirectoryA"
(ByVal lpPathName As String) As Long

The "kernel32" part is the name of the DLL containing the function, and
SetCurrentDirectoryA is the name of the function in the DLL.

If you are not sure of the declaration required, post the C/C++ declarations
that are exported by the DLL. There are some people on this site who can then
tell you what the corresponding declarations in VB should be.
